1 Claim,

This invention relates to a folding vise stand and has for one of itsobjects the production of a simple and efficient folding vise standhaving a maximum strength and so constructed as to eliminate lost motionwhen in a set-up position, the stand being light in weight and beingeasily and quickly set-up.

A further object of this invention is the production of a simple andeicient vise stand espeeially adaptable for use by plumbers and thelike, one important feature being the bracing element between thefolding legs and the visesupporting table.

Other objects and advantages of the present invention will appearthroughout-the following specification and claim.

In the drawing:

Figure 1 is a perspective View of the stand in a set-up position; a,certain portion thereof being shown in section;

Figure 2 is a side elevational view of the stand in a folded position, acertain portion being shown in section;

Figure 3 is a horizontal sectional view taken on line 3 3 of Figure 2;

Figure 4 is a vertical sectional View taken on line 4 4 of Figure 3;

Figure 5 is a. vertical sectional view taken on line 5 5 of Figure 1;

Figure 6 is a horizontal sectional View taken on line 6 6 of Figure 1;and

Figure 7 is a vertical sectional View taken on line I 'I of Figure 6.

By referring to the drawing, it will be seen that I0 designates thetable portion or table top of the vise stand which 'is preferably squarein formation having beveled side edges II. Three ribs I2 are formed uponthe bottom of the table top I6 and are preferably formed integraltherewith, and these ribs are arranged to provide a Y-shaped channel I3upon the bottom face of the table I6 so as to support the front leg atan angle of approximately twenty-two and one-half degrees with respectto the sides, and the back legs at approximately a ninety-degree anglewith respect to the back of the table.

Legs I4 are pivotally secured within the Y- shaped channel between theribs I2, as shown in Figure 3, the legs being pivotally secured inposition by means of bolts or other securing means I5, the legs beingpreferably three in number. These legs diverge from each other at theirlower ends and are provided with notched feet I6 through which feet mayextend anchoring screws Il, or other suitable anchoring ele- 24e-fin)ments A hollow depending tubular guide or pipe I8 is secured to thecenter of the table top II] and extends therethrough, as shown in Figure4. A lock nut I9 is threaded upon the upper end of the tubular guide I8and abuts against the under face of the table top I0 and a beveledwasher 20 is threaded on the extreme upper end of the tubular guide I8to lock the guide firmly in engagement with the table I0.

A vertically extending bracing rod 2I is slidably mounted through thetubular guide I8 and this bracing rod 2l is provided with a threadedupper end 22, and a threaded lower end 23. A slidably mounted collar 24is carried by the lower end of the bracing rod 2I and abuts against thelower end of the tubular guide I8 When the table is in a set-upposition. A binding nut 25 is threaded upon the lower threaded end 23and engages the collar 24 to hold the collar 24 in abutting relationwith respect to the lower end of the tubular guide I8 when the table isin a set-up position.

A plurality of flat radiating braces 26 are hingedly secured, as at 2l,to the collar 24 at their inner ends, and the braces 26 are hingedlysecured at their outer ends, as at 28, to the legs I4, as shown inFigures 1 and 7. These braces 26 may be of suitable design toefliciently brace the legs I4 when in an extended position, and at thesame time constitute a securing element when the legs are in a foldedposition, as is shown in Figure 2. A nut 29 engages the upper threadedend 22 of the bracing rod 2I when the table is in a set-up position andthis nut is engaged by a swivel link 38, which swivel link is anchoredto a chain 3|, the chain 3| being secured, as at 32, to the under faceof the table.

The table portion I6 may be provided with a bead IIa around the upperedge thereof to hold articles, such as oil cans and the like, on the toppart of the table, and prevent them from slipping off the table.

From the foregoing description it will be seen that a very simple andeflicient, as well as sturdy, vise stand has been provided which willvery firmly and securely support the table IIJ when the legs are in anextended position, as is shown in Figure 1, and it will also be notedthat the rod 2l will constitute an efficient brace when the nuts 29 and25 are threaded on the respective ends 22 and 23 and are moved to abinding position. When it is desired, however, to transport the standfrom place to place, the nut 29 may be removed and the bracing rod 2Imay slide down into the tubular guide I8, as shown in Figure 2,

thereby permitting the legs I4 to be swung to an approximately parallelposition. When the vise stand is in a set-up position and the screws I'Iare anchored into the oor or other support, and the nuts 29 and 25 arethreaded into binding position, the table will be rmly and thoroughlybraced. For temporary Work, however, when the nuts 29 and 25 arethreaded to a binding position and the legs I4 are moved to the positionshown in Figure 1, the parts will be suiciently braced Without theanchoring screws I1 to provide a sturdy and efficient support. When thescrews I'I are used, the notched feet I6 will be forced rmly against thescrews as the nut 29 is threaded down upon the upper end 22 of the rod2I. The table I0 may be provided with suitable apertures 33 and 34 toreceive anchoring means for a vise or other element or tool which may bemounted upon the table II.

From the foregoing description it should be understood that certaindetail changes in the construction and arrangement of parts may beemployed without departing from the spirit of the invention, so long assuch changes fall Within the scope of the appended claim.

Having described the invention, what is claimed as new is:

A folding vise stand of the class described comprising a table top,spaced integral ribs arranged to form a, Y-shaped channel upon thebottom face of the table, legs pivoted in said channel between the ribsand adapted to be extended in diverging relation to support said tabletop, the legs having means for anchoring the lower ends thereof to asupport, a hollow tube depending from and extending through the tabletop, a bracing rod having an inner end slidable in said tube, radiatingat braces horizontally hinged to said rod at one end and to the legs attheir opposite ends to resist lateral strain when the legs are in anextended position, and means engaging the inner end of the rod andabutting the top face of the table top to hold the rod in a set positionwithin the tube and thereby preventing the legs from spreading.
